While duder is *undeniably* a massive toolbag, does none of the blame fall on Samantha for having sex with her best friend's boyfriend? Unless he had some magic irresistible charm, or raped her, I think she did plenty herself to toss that BFF necklace in the trash. I understand it's hard to view someone close to you in such a light, but Samantha was being a pretty shitty friend.
